Do you have a device /dev/ttyUSB0? That's normally where a Vantage shows up in the device directory, but not always.
The most reliable way to find out where the Vantage ended up is to unplug it, plug it in again, then type 'dmesg'. This will look something like: *dmesg* [14818.699217] usb 2-2.1: USB disconnect, device number 4 [14818.699660] pl2303 ttyUSB0: pl2303 converter now disconnected from ttyUSB0 [14818.699710] pl2303 2-2.1:1.0: device disconnected [14820.731608] usb 2-2.1: new full-speed USB device number 10 using xhci_hcd [14820.844750] usb 2-2.1: New USB device found, idVendor=05ad, idProduct=0fba, bcdDevice= 3.00 [14820.844756] usb 2-2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [14820.844759] usb 2-2.1: Product: USB-Serial Controller [14820.844761] usb 2-2.1: Manufacturer: Prolific Technology Inc.
